How do you use candidate Q&A in OBI criteria?

Summary:

I need to modify an existing analysis to include candidates who answered two questions in a certain way.

I know the Question Code/Description and have no problem including them or the Answer Choice (BL) in the report.

However, I'm having problems using them as criteria.

For example, I need Question Code A to have a response of "Yes" and Question Code R to have a response of "Whatever".

I've tried grouping them different ways, etc. but I have a feeling that I'll need to use a SQL expression.

I've tried this in many different ways, but none seem to work.
